情報記録媒体再生装置。[Claims for utility model registration]
An information recording medium reproducing device having a raster signal generation circuit for making a V screen into a raster state, the information recording medium reproducing device comprising: a reference signal generation means for generating a reference signal; and an internal synchronization based on the reference signal generated by the reference signal generation means. internal synchronization signal generation means for generating a signal; raster synchronization signal generation means for generating a raster synchronization signal for the raster signal generation circuit based on a reference signal generated by the reference signal generation means; Detecting the deviation between the internal synchronization signal and the raster synchronization signal due to synchronization with the reproduction synchronization signal from the information recording medium until the deviation falls within a certain range that does not cause vertical drift of the TV screen. 1. An information recording medium reproducing apparatus comprising: synchronization means for synchronizing the raster synchronization signal with the internal synchronization signal after bringing the raster synchronization signal close to the internal synchronization signal.
